Answer 1

Both statements are correct.

1. The rough endoplasmic reticulum (ER) is covered in ribosomes, giving it a rough appearance, while the smooth ER lacks ribosomes, giving it a smooth appearance.
2. The rough ER is involved in protein synthesis and processing, while the smooth ER is involved in lipid synthesis and detoxification processes in the cell.
